Algebra Name: Piecewise, Absolute Value, and Step Functions Review. Carefully graph each of the following. Then evaluate the function at the specific value. Write equations for the piecewise functions whose graphs are shown below. 8.
Functions. Write as a Function of y. y = x + 2 y = x + 2. To rewrite as a function of x x, write the equation so that y y is by itself on one side of the equal sign and an expression involving only x x is on the other side. f (x) = x +2 f (x) = x + 2. Enter YOUR Problem.
Piecewise defined functions can take on a variety of forms. Their "pieces" may be all linear, or a combination of functional forms (such as constant, linear, quadratic, cubic, square root, cube root, exponential, etc.).
3.3 Piecewise Functions Use the piecewise function to evaluate the following. 1. 𝑓(𝑥) = −2𝑥2−1, 𝑥 𝑥≤2 4 5 𝑥−4, 𝑥> 2 2. 𝑓(𝑥) = 3 −7 𝑥, ≤ 3 8, −3 < 𝑥≤3 √2𝑥+ 3, 𝑥> 3 𝑎. 𝑓(0) =
A piecewise function is a function where more than one formula is used to define the output over different pieces of the domain. Evaluating a piecewise function means you need to pay close attention to the correct expression used for the given input.
